Update of /sources/public/html5/spec
In directory hutz:/tmp/cvs-serv9690
Modified Files:
infrastructure.html spec.html
Log Message:
Fix the UTF-8 decoder error handling to handle a few errors I'd missed, including in particular surrogate halves. This may be a mistake; if I'm forgetting something please let me know so I can fix it. (e.g. did we decide not to catch surrogates or something?) (whatwg r5942)
